Steel 1119-A vs 1119-CD
Steel · 1119 temper comparison
1119-A and 1119-CD are two conditions of the same steel grade, 1119: A (solution annealed) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 1119-CD is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 250 MPa (36.3 ksi) for 1119-A, about 66% more; tensile strength follows at 495 MPa (71.8 ksi) vs 400 MPa (58 ksi). In exchange, 1119-A is the more ductile: elongation 30% versus 15% for 1119-CD, and 1119-CD is harder (143 HB vs 116 HB). On the shop floor, 1119-CD machines more easily (95 vs 85 out of 100).
1119-AChoose it when the part is bent, formed or impact-loaded.
1119-CDChoose it when strength drives the design, or when the part is machined in volume.
1119-A vs 1119-CD: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

1119-A vs 1119-CD — frequently asked
Is 1119-CD stronger than 1119-A?
Yes. 1119-CD has a typical yield strength of 415 MPa (60.2 ksi) against 250 MPa (36.3 ksi) for 1119-A — about 66% more. Tensile strength is 495 MPa (71.8 ksi) vs 400 MPa (58 ksi).
Which condition does FabDigit quote by default, A or CD?
CD is the default 1119 condition in the FabDigit quote flow. The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, 1119-A or 1119-CD?
1119-CD, by a small margin. Both rate excellent for machinability — 95/100 against 85/100 for 1119-A.
